Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer manufacturing, and in particular to a transformer oil collection tank base and its connection structure. Background Technology
[0002] In power system operation, transformers are critical equipment, and their safety and stability are paramount. The oil collection tank base and its connecting structure are essential components for ensuring the safe operation of transformers. Existing transformer oil collection tank bases and their connecting structures have several shortcomings: First, the oil collection structure design is inadequate. Some bases lack effective partitions, or the oil collection chambers are independent and lack interconnection, making it difficult to collect leaked oil from the transformer, leading to widespread spillage. This not only increases cleaning difficulty but also poses a risk of oil leakage polluting soil and water bodies. Second, because the base is a closed structure (for oil collection and drainage), there is no dedicated space for bolt installation. Therefore, the connection between the transformer body and the base often uses a welded structure, making subsequent separation difficult, affecting installation efficiency and increasing subsequent maintenance costs.

[0018] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] like Figure 1-4 As shown, a transformer oil collection tank base and its connecting structure include a base 1 and a transformer body 2. The base 1 is provided with multiple sets of partition plates 3 to form oil collection cavities 4. The partition plates 3 are provided with through holes 5 to connect the multiple sets of oil collection cavities 4. A sealing plate 6 covers the oil collection cavities 4. The middle part of the base 1 without the sealing plate 6 forms a transformer installation area 7. The front and rear partition plates 3 of the transformer installation area 7 are provided with vertical base fixing holes 301. The bottom of the transformer body 2 is provided with horizontal fixing holes 201 corresponding to the vertical base fixing holes 301. The vertical base fixing holes 301 and the horizontal fixing holes 201 are fixedly connected by bolts. A sunken sealing plate 8 is provided in the oil collection cavity 4 outside the front and rear partition plates 3 of the transformer installation area 7. The sunken sealing plate 8 is located on the side of the partition plate close to the transformer installation area 7. The sunken sealing plate 8 and the sealing plate 6 seal the oil collection cavities before and after the transformer installation area.
[0022] like Figure 1-2As shown, the two sets of partitions 3 in the transformer installation area 7 are provided with extension plates 9 on the outside. The vertical base fixing holes 301 are opened on the extension plates 9. A rubber layer is provided between the extension plates 9 and the bottom of the transformer body 2. The extension plates increase the contact area between the base and the transformer body, disperse the stress generated by the fixing bolts, and avoid structural damage caused by local stress concentration. At the same time, the rubber layer has good elasticity and sealing properties. On the one hand, it can fill the small gaps between the extension plates and the bottom of the transformer body to prevent oil leakage. On the other hand, it can buffer the vibration generated during transformer operation, reduce vibration transmission, reduce noise, and enhance the stability and seismic performance of the overall structure.
[0023] like Figure 1-2 As shown, the base 1 has an oil drain hole 10 on its side. When the transformer leaks, the oil is collected in the oil collection chamber and then discharged through the oil drain hole, preventing the oil from flowing to the outside. The setting of the oil drain hole 10 realizes the directional discharge of the leaked oil, which is convenient for centralized recycling and treatment, and prevents the oil from polluting the soil, water and other environments.
[0024] like Figure 1-2 As shown, the area above the sunken sealing plate 8 is a hollow cavity forming a bolt mounting area. When the transformer body is connected to the base, the area above the sunken sealing plate facilitates the fixing of bolts.
[0025] like Figure 1 As shown, the transformer body 2 is placed on the partition plate 3 on both the left and right sides and abuts against the edge of the sealing plate 6. This design limits the transformer body from the left and right directions to ensure that it will not move laterally during operation and maintain the stability of the equipment operation.
[0026] like Figure 2 As shown, multiple sets of support beams 11 are provided in the transformer installation area 7, which are used to support the transformer body.
[0027] The working principle of this utility model is explained as follows: When oil leakage occurs during transformer operation, the leaked oil first flows into the oil collecting chamber formed by the partition plates on the base. The partition plates are provided with through holes, allowing the oil to flow freely and collect between the oil collecting chambers, and finally be discharged through the oil drain hole on the side of the base. This achieves directional collection and treatment of the leaked oil, avoiding environmental pollution or safety hazards caused by the oil.
[0028] When installing the transformer body, align the horizontal fixing holes at its bottom with the vertical base fixing holes on the extension plate on the base, and tighten the bolts through the fixing holes to achieve a stable connection between the transformer body and the base. The hollow cavity above the sunken sealing plate serves as a bolt installation area, providing ample space for fixing the bolts, facilitating precise alignment and tightening of the bolts during installation, and improving installation efficiency and connection accuracy.

Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
